Dr. Philip Kaaret’s main interest is understanding the intense gravitational fields surrounding black holes and neutron stars and the dynamics of the accretion of matter onto these objects. He builds instrumentation for the X-ray and gamma-ray bands and conducts observations at X-ray, gamma-ray, optical, and radio wavelengths of objects in our Milky Way Galaxy and in relatively nearby galaxies. His current work concerns the highly luminous X-ray sources in nearby galaxies which have been interpreted as being intermediate-mass or "medium-sized" black holes and the effect of X-ray binaries on the early universe.

Bio ▼
Dr. Julia Kamenetzky is currently a National Science Foundation Astronomy & Astrophysics postdoctoral fellow at the University of Arizona, where she is using radio and submillimeter telescopes to study the emission from molecules in nearby star-forming galaxies. By modeling the emission, Dr. Kamenetzky and her colleagues can try to estimate what processes are influencing the gas spread throughout the galaxies and how that affects star formation. She has also used similar tools to study molecules that were formed in the debris left behind form the explosion of Supernova 1987A. Her other professional interests include science policy, inquiry-based science education, and tackling the barriers that prevent many people from understanding, appreciating, or pursuing science as a career.

Bio ▼ |
Dr. Bharat Ratra is a professor of physics at Kansas State University, working in the areas of cosmology and astroparticle physics. He researches the structure and evolution of the universe. Two of his current principal interests are developing models for the large-scale matter and radiation distributions in the universe and testing these models by comparing predictions to observational data. In 1988 Dr. Ratra and Jim Peebles proposed the first dynamical dark energy model. Dark energy is the leading candidate for the mechanism that is responsible for causing cosmological expansion to accelerate. The discovery that cosmological expansion is accelerating is one of the most significant discoveries of the last quarter century.

Bio ▼ |
Dr. Luisa Rebull always wanted to be an astronomer. She “fell off the wagon” for a long time in elementary school because she believed that “girls can’t do math.” It took her until college(!) to get over that mentality. She went to the College of William and Mary in Virginia for her undergraduate degree (and still remembers when a Shapley Lecturer came to visit), and to the University of Chicago for graduate school. Dr. Rebull studies how stars like our Sun form, with an eye towards understanding how planets form. She uses telescopes on the ground and in space, and uses wavelengths from X-rays to infrared, but has most recently focused on infrared. She really enjoys sharing what she does with the general public, and feels strongly that since the taxpayers help pay her salary, they deserve to find out what she does in terms they can understand. Dr. Rebull also runs a program called NITARP that partners small groups of (mostly) high school educators with a research astronomer for a year-long research project.
